The wrong Brexit deal could cost tens of thousands of jobs, the boss of Britain’s biggest carmaker Jaguar Land Rover warned on Tuesday, saying he had no idea whether his plants would be able to operate after Britain leaves the EU on March 29 next year.

One of NASA’s robot rovers on Mars has been silenced as a massive dust storm roars across the Martian surface. With its power source — the sun — obscured, the rover Opportunity, “has gone to sleep,” said John Callas, project manager at NASA’s Jet Propulsion Laboratory.

By Will Dunham WASHINGTON (Reuters) – An immense dust storm that may soon encircle Mars is threatening one of NASA’s rovers on the planet’s surface, with the vehicle becoming dormant and unresponsive at a site called Perseverance Valley, U.S. space agency officials said on Wednesday. The officials, however, expressed optimism that the Opportunity rover, which was built to operate for three months but has thrived on Mars since January 2004, will be able to survive and continue its scientific mission. John Callas, Opportunity project manager at NASA’s Jet Propulsion Laboratory in California, said the solar-powered rover, with the sun blotted out by an intensifying dust storm already engulfing a quarter of Mars, is no longer responding to commands.
